[pianotech] buzzing lid hinge

[John Ross]

How about a tap with a punch, which compresses the part the pin fits in?

  Mark,

  I'd suspect that with as much play as you are describing that you've got a mismatch between the hinge and the pin.  See if you can't figure that out and then (hopefully) just order the proper pin.  Worst case scenario I suppose would be having to replace the hinge/pin assy.  But, I'd bet you could just mic the pin and find one that is slightly larger.  

  And, as Ed suggests, give a call to M&H.

    I have a new Mason & Hamlin AA where the long lid hinge has quite a bit of play between the pin and the hinge halves. The remedies that I have heard for this problem in the past are to remove the pin and put a gentle bend in it or else to slather it with vasoline or something similar. Can anyone comment on the efficacy of either of these methods or offer alternative suggestions? I don't think that bending the pin will help in this case, as there really is quite a lot of movement between the pin and the hinge, and I don't really like the idea of smearing vasoline around.
